 |
|
Hi everyone!
I've made an online tool to make .map files for any part of the world with a point-and-click interface. It's not a greatly usable piece of software, but it gets the job done! Any comments and suggestions are absolutely welcome!
A screenshot is attached and the [changed] URL is: http://www.mapcacher.com/

Hi Shustrik,
This is a great tool, and could be a big step towards a GUI map tile downloader. A few thoughts and suggestions in some random order:- Process double-click events and handle them the "usual way" (zoom-in or out), instead of placing two markers on the map when the user double clicks.
- Try to redesign the page a bit to make it fit all the form elements at 1024x768 and 1280x800. For example, you could move the ads to the left/right, or you could make the map a bit smaller (maybe auto-sized based on browser size).
- Processing of non-convex polygons is sometimes incorrect, there's a small area that's selected but not covered by any rectangle. It only happens in some cases - see the screenshots attached.
- As I said, this could be a step towards a GUI downloader. Here's how I envision it to work: the users visit your page, select the map to download and get a .map file (they should be able to download the info as a file instead of copy/pasting it); then they open the file with a GUI that downloads all the needed map tiles. The big advantage here is the fact that the GUI does not need to display a map or allow the user to choose the coordinates, so it would be a lot easier to design based on the perl scripts.
Best regards,
Cristian

This was rather tough, as Google doesn't separate the Double Click event from the Click event, which results in the fact that there are 2 or 3 events (depending on the browser), that can also have different click locations... Anyway, the result is that now there is an additional 0.5sec delay between a click and a marker appearing. This doesn't prevent a user from fast line drawing - You can still click points all around, they're just going to appear no sooner than in half a second

There indeed was an issue there, which has to be fixed now. However, due to the imprecision of the map projection (I'm pretty sure I wouldn't have made the Earth round if it were my decision ), it sometimes happens, that a part of the selected area appears to be outside the area that the script has deemed to be mappable. You can just zoom in and see close-up that all the parts of the polygon are in fact in their respective rectangles

Hi
Why is it that when I run MapTileFE and select the included .map file of Tokyo I get an error "cant open perl script MapTileCacher.perl no such file or directory" when both programs are there in the same folder and Maptilechacher will run separately but is not activated by maptilefe?
Thanks

Make sure your current folder is the same as the one containing the scripts and the .map file.

Thanks  Hope you don't mind me pointing out a bug - marker moving doesn't seem to work fine, only the last marker moves correctly, the other move independently of selected area bounds. See attached screenshot.

Great, it looks fine in IE, overlaps with the ads in Firefox (but with Adblock enabled looks fine again).

That's okay, thank you!

Great again! Now all that's left (for me) to do is write that GUI for Windows to read .map files and download the tiles...

Cristian
the .map file, maptilefe.pl and maptilecacher.pl are all in the same folder
but running maptilefe stating .map file doesnt start maptilecacher
any ideas..?

Your script name is MapTileCacher.pl, while MapTileFE refers to MapTileCacher.perl

I was asking for the Shustrik's .map Creation Tool to have mouse scroll wheel action. 
| Code: | | map.enableScrollWheelZoom(); |

By default it caches one map tile per file, but you can configure it to cache 32.

Spent some time to find out how to handle scroll wheel events in both Firefox and IE, but now it works great - zooms in/out when the mouse pointer is inside the map and scrolls the page when outside in both browsers

Ah, that wasn't easy. I had the same problem with gmap-track but I just resized the map to make sure the entire page always fits the screen.

Here is the code in case You need it again someday:
| Code: | var mouseinside=false;
function mousewheel(event){
if (mouseinside) {
if (event) {
if (event.preventDefault && (Function == event.preventDefault.constructor))
event.preventDefault();
event.returnValue = false;
}
return false;
} else {
return true;
}
}
if (window.addEventListener)
window.addEventListener('DOMMouseScroll', mousewheel, false);
window.onmousewheel = document.onmousewheel = mousewheel;
GEvent.addListener(map, "mouseover", function(point) {
mouseinside = true;
});
GEvent.addListener(map, "mouseout", function(point) {
mouseinside = false;
}); |
